ed for use in the corners of rooms near the ceiling whereby foul or stagnant air may be expelled.

Other objects andadvantages will be apparent from the following description and it will be understood that eliangesin the specific structure shown and described may be made within the scope of the ole ims without departing from the spirit of the invention.

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a perspective view of the present ventilator, Fig. 2 is a perspective view of one member of the ventilator, Fig. 3 is a perspective view of the other member of the ventilator, Fig. 4: is a detail sectional View showing the application of my invention to the ceiling of a room or the like.

Referring now more particularly to the drawings, there is shown a ventilator 5 com prising two members 6 and 7 respectively. The member 6 is stamped from asiugle piece of sheet material and bent to form right angularly disposed port-ions 8 and 9 respec tively. The portions 8 and '2) respectively are provided at their outer ends with vertically disposed portions 10, and below these portions 10 the edges ofthe portions 8 and 9 are scalloped as shown at 11 or otherwise cut to present an ornamental appearance. The portions 8 and 9 of tl'iemember '6 are provided adjacent to their edges with passages 12 for thereceptionof fastening devices, not shown. The member 7' is also stamped from a single sheet of material and comprises a vertically disposed portion 13 and an inwardly directedtriangular portion 14.- arranged to lie with its edges engaged with the ed es of the portions 8 and 9 re: spectively'o the member 6. Ate-ash end, the portion 13 of the member 7 is provided with a flange 15 which may be conveniently attached by means of fastening devices 16 to the portions 10 of the member 6. The portion 14; is provided with a plurality of perforations 17, and the portion L3 adjacent to its upper endis preferably provided with a plurality of similar perforations 18. The portion 17 is provided with a depending portion 19 having its lower edge scalloped as shownat 20, to present an artistic design. In Flgfil of the drawings, there is shown the corner of room A lncludlng its celhng B which is provided with a'passage C which maybe in communication with a suitable air duct if found desirable. It will thus be seen that the triangular portion 14 of the member 7 is disposed directly beneath the passage C formed in the. ceiling, and it will thus be seen that foul or stagnant air which generally seeks the highest point in a room and at the corners thereof may be effectively expelled through the passages 17 and discharged through the passage C.

A device as herein set forth and described is extremely simple in construction, may be stamped from suitable sheet material, thus reducing its cost of manufacture to a minimum.

While the portions 8 and 9 of the members 6 arepreferably right angularlydisposed it will of course be understood that these portions of the member may be curved to conform to the curvature of rooms of different adjacent to the outer end of said horizontally disposed portiomsaid depending portion being arranged to lie in spaced relation to the Walls of a room.

2. A ventilator of the class described comprising a member having angularly disposed portions, a member secured to said first named member and including a portion arranged to close the upper end of said first named member, said last named member having a plurality of discharge passages therein and a vertically disposed portion carried by said last named member and arranged to close the front of said first named member adjacent to its upper end.

5 3. A ventilator comprising a metallic memher having angularly disposed portions, a metallic member having its ends engaged with said angularly disposed portions adjaeent to their upper ends and an inwardly 10 directed portion carried by said last named In testimony whereof I afiix my signature,

in presence of two witnesses.
